Introduction

• Supported OpenSearch versions: 1.x, 2.x

OpenSearch maintains API compatibility between versions and remains compatible primarily with Elasticsearch v7.10.2 this version compatibility is automatically retrieved from root/ping endpoint. Based on this version Jaeger uses compatible index mappings and OpenSearch REST API.

OpenSearch does not require initialization other than installing and running OpenSearch . Once it is running, pass the correct configuration values to Jaeger.

OpenSearch also has the following officially supported resources available from the community:

• Docker container  for getting a single node up quickly
• Helm chart 
• Kubernetes Operator 

Configuration

Here is example configuration  for OpenSearch. Overall Jaeger uses the same implementation for OpenSearch as for Elasticsearch, so most of the discussion on the Elasticsearch page applies.
